Session Bean не работает

Question

У меня есть SessionBean и вы хотите загрузить DATA из класса InfoHolder под названием Benutzer. Но это не сработает.

     return user; 
    } 

    public void setUser(String user) { 
     this.user = user; 
    } 

    } 

Это действительно работает.

Но когда я использую bntzr ..., тогда ничего не работает:/ Есть ли нетривиальный пример?

Answer 1

Используйте это: group52.infoholders.Benutzer.

Есть ли функции getter и setter, такие как: public Benutzer getBenutzer() {return bntzr; } public void setBenutzer (Benutzer bntzr) {this.bntzr = bntzr; }
